I get a popup box saying my computer is infected and should scan it with Vscan7. Anyone know what this is and?

I have a similar problem sometimes. I would definatley suggest that you DO NOT CLICK ANYTHING and immediately shut down your computer. Once you restart it open your own antivirus protection program and do a FULL SYSTEM SCAN. Doing the quick scan can cause you to miss something that could be potentially hazardous to your computer. If your full scan comes back clean then you will know that the original "pop-up message" was the virus. Clicking on it would have downloaded it to your computer. If you get this pop up box again in the future then follow the steps that I suggested above. Never trust any popups.

Personally- when this happened to me my computer told me that it was "Windows" and it detected over 100 trojan infections on my harddrive and that by clicking on it, it would fix itself automatically. I did exactly what I told you to do and my computer has been just fine. Oh, there is really no way to make it stop. Just be careful of the website you are on. Among others I think it happens most frequently on Myspace, Facebook, and Youtube. Hope this was helpful!

Disregard the first guy.

This program, Vscan7, is the virus itself. It asks you to scan, and when you do, it gives you viruses. Exit out as quickly as you can. Then download AVG Free virus protection and do a scan with it.

Use a good commercial anti-virus program, NOT the one in the pop-up.

That pop-up is a symptom of a malware infection.

Going to the site it prompts will just get you more mal-ware.

That's just a virus. if it starts on it's own, then try clicking again and keep closing it. Try shutting your computer down.

you have a virus.. download this program malware bytes antimalware

then do a quick scan then a full scan

It's like a hijacker
